GAS HEATER Filed June 14, 23

Patented Feb. 3, 1931 UNITED STATES HENRY H. M ORET'ON, OF SANTA MONICA, CALIFORNIA ens HEATER Application filed. June 14,

This invention is a heater of thetype in which a gas flame is employed as the primary source of heat.

One of the objects of the invention is to provide a heater element located at a predetermined focal position with respect to a circular heat-reflector element, and to so construct said heater element as to insure a maximum heat transference from a gas flame for heat radiating purposes. A further object 1s to provide simple and eflicient means for supporting the heater element in its proper focal position with respect to the reflector. A further object is to provide simple means for d1- recting one or more gas flames against the heater element.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing Figure 1 is a front elevation illustrating a heater constructed in accordance with the invention. Figure 2 is a transverse sectional view thereof. Figure 3 is a detail view illustrating the heater element supporting means.

Referring to the drawing, 10 designates a base upon which is pivotally mounted a reflector 11, friction means 12 being provided so that the reflector may be held at any desired angle with respect to the surface on which the base rests. Means, indicated at 13 is provided however, to limit downward adjustment of the reflector to prevent the heat being directed upon said surface. The reflector is constructed of anydesired metal capable of performing the functions, and is preferably shaped in the form of a circular concavo-convex disk.

The heater element consists of a hollow body 14 of refractory material, preferably of conical form, the base of the cone forming the front wall of said body, the apex of the cone being directed toward the reflector and positioned opposite the center thereof. In practice, said heater element is positioned as nearly as possible at the focal point of the disk or reflector, and is supported by means of a cradle formed of two oppositely extended arms 15, provided with flanges 16 shaped to 50 fit the exterior portion of said element. I Said 1928. Serial No. 285,477.

arms areattachedto or. formed with a standard17, pivotally mounted at its lower end in a bracket 18, secured to the. periphery of the reflector. Said standard is held inany a'djusted position by means of a clamping screw 19, as shown. It will be observed that the arms 15 are widened at their outer ends, so

that the flanges 16 are extended to a position below the axial center of the heater element in the upper portion thereof.

The heater element is heated by means of 2.. 0

two Bunsen burners B, conventionallyillustrated, bothconnected to a gas pipe 21 supported by a bracket'22, carried by the lower portionof the reflector. Said pipe 21 is prov ded with 'a cook 23, and also with a nipple 24 by means of which it may be attachedt'o the usual flexible tubing. It is to be understood that although two burners are shown, this'number wasselecte'd solely for purposes of illustration. However, the invention is not limited to the use of'this number of burners, because the number may be increased or diminished without departing from the spirit of the invention.

In operation, the Bunsenburners are adjusted to insure a mixture that will provide the' maximum available heat, and the burners are so positioned that when the gas mixture is ignited the flames will be directed against the heater element 14:. In time said heater heat rays emanating therefrom will impinge against the concave surface of the reflector, and be so reflected thereby as to be distributed in a uniform and eflicient manner into the space to be'heated.

The advantages of the invention will be readily apparent to those skilled in the art to which it belongs. For instance, it will beparticularly observed that a very eflicient form. of heater element is provided, by means element will become incandescent, and, the

of which the initial heat of a Bunsen flame is greatly magnified, and directed against the reflector surface from a position to be uniformly reflected into the space to be heated. In addition to this, very simple means are provided for supporting the heater element in the desired focal position with respect to the reflector, in a manner that permits of its ready removal and replacement if occasion should require.

Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set. forth all of the forms in Which it may be made, or all of the forms of its use, What is claimed is 1. A heater of the character described comprising a reflector member, a refractory heater element of conical form, a cradle for supporting said heater element in a pre determined focal position with respect to said reflector and with the apex of the cone projected toward the reflector surface, and means for applying heat to said heater element.

2. A heater of the character described comprising a reflector member, a hollow heater member of refractory material provided with perforations in its walls, means for supporting said heater element in apredetermined focal position with respect to said reflector,

and means for applying heat to said heater element. V

3. A heater of the character described comprising a reflector, a standard connected with said reflector, and provided with, laterally extended arms forming a cradle, a heater element of refractory material removably mounted in said cradle and supported in a predetermined focal position with respect to said reflector, and means for applying heat 'tosaid heater element.
